IMPROVEMENT IN CAR-COUPLINGS.

Nature of the Invention.

which is attached a chain or cord E, which passes over pulley G, and is secured at the opposite end to the head of coupling-pin G.

The lower end of this lever is formed with atogglc, c, and has a spring, 8, attached to the upper, and connected to the lower, section by a loop, t, or equivlcnt. This toggle stillens inwardly, but yields outwardly, and the spring serves to give it the proper degree-of tension. v

The operating parts are inclosed in an outer casing or box, N, secured to the draw-head.

An independent chain, S, attached to the head of the coupling-pin, and extending up through opening a of the outer casing N is employed to raise the pinin uncoupling. 1

The head of the pin is provided with lugs 1) 1), which slide in vertical grooves r r of the bearings, and thus keep the pin in place.

\Ve contemplate, in some instances, to attach one. or both draw-heads to the frame of the car, by .downwardly-projecting bearings, with adjustable holes in the front one, by which the angle of the month may be changed by simply removing a pin and inserting in another hole. Thisis to accommodate to cars of diii erent heights.

The operation is as follows:

The link K, on entering the draw-head, first strikes against and pushes back the toggle c, causing the same to become rigid, and making the lever D to turn, thereby drawing the chain E over pulley O, and raising the coupling-pin a suflicient distance to allow the link to pass under. As soon as the end of the link has passed under and left the toggle c, it is carried by the mo- 7 mentnm beyond and under the coupling-pin G, which latter, now having nothing to withold it, falls into its former position by its own gravity, thereby. securely locking the link.

\Vhen it-is desired to nncouple or withdraw the link, the coupling-pin G is raised by means of the chain S, which extends out through the casing N to the hands of the operator. In its withdrawal the end of the link comes in contact reversely with the toggle c, causing the same to yield until the link frees, when the spring causes thetoggle to assumeits normal position, when it is ready for use again.

- An advantage rests in the use of this coupling, from the automatic action, whereby no force or concussion can be brought upon the coupling-pin itself, by which it may become bent or broken.

The lever serves as the pioneer of action, and the coupling-pin only follows its movements. Thelink never comes in contact with it in entering.

A special advantage,however, results, and to which we lay a claim, in theuse of the toggle at the lower end of the lever.. \Vere it not for this, the'device would be inoperative.

What we claim, and desire to secure by Patent, is-

The togglb c and spring s, combined with the lever 1), chain or co-rd E, pulley G, and coupling-pin G, the whole arranged as described, and operating in the manner and for the purpose specified.

In witness whereof, we have hereunto set our hands this 23d day of May, 1870.
